UNITED STATES PATENT OFFICE PHILIPPE GENGEMBRE HUBERT, OF NEW YORK, N. Y.

IMPROVEMENT IN PLASTERING WALLS.

Specification forming part of Letters Patent No; 154,179, dated August 18, 1874; application filed Avril 3, 1874.

To all whom it may concern:

Be it known that I, PHILIPPE GENGEM- ERE HUBERT, of New York, N. Y., have invented an Improvement in Plastering Walls, Ceilings, &c.,of which the following is a speciication:

This invention relates to that class of plastering used in the art of building, in which a sheet of ibro-ligneous substance is used as a foundation or back for receiving the stucco or hard-huish; and it consists in the mode of plastering wherein said foundation or back is stuck or cemented to the wood-work by a pitchy or resinous cement, or by plaster-otparis or other calcareous cements.

In my application for Letters Patent of the United States filed February 11, 1874, and patented March 17, 1874, No. 148,562, I describe the fibro-ligneous foundation as nailed upon the wood-work, which meets the case for certain work; but, when the wood-Work is lightas, for instance, in the case of lathed partitions or ceilings-the nailing is not always advantageous, andI prefer to stick or cement said foundation to the wood-work with apitchy, resinous, or calcareous cement, as hereafter described.

In my drawing accompanying this specification, Figure I represents a ceiling or partition in process of plastering by my im proved method, and Fig. II is an enlarged representation of the same. (Shown in section through the width of the laths, as per line K K.)

I have used the same letters to indicate like parts in this and my other application above referred to in order to avoid confusion.

A represents the wood-work or laths, B, Y

the iibro-ligneous back or foundation, and G the coat of stucco or hard-finish. P represents a coat of cement, which may be either of a resinous, pitchy nature, or a calcareous cement of plaster-of-paris, hydraulic lime, Src., according to wants of the Work, Whether the foundation is to be a felt, a paper, a pasteboard,

prepared wood, sheets, mattings, plaited rushes, or other ligneous substances, wrought into sheets dry, or previously coated With resinous or pitchy cements.

The cement P is applied either upon the wood-work, or upon the flbro-ligneous sheets, or on both; and the sheets of foundation are applied on the Wood-work, and thereagainst held or pressed until, by setting, the said cel lnent P sticks, or is firmly retained against the Woodwork of the aforesaid foundation,which V I is then ready to receive the hard-f1nish or stucco. Disclaimin g anything I may have described P. GENGEMBRE HUBERT.
